Hi taddee,
I'm sorry for not getting back to you sooner. If you want to do it with the assistant option you'll need to download the config.yml again, modify it with the new indexer nodes data and rerun the wazuh-install.sh script, as shown in this
link.
For the server case, you can do it with the assistant too. You'll need to modify the previously downloaded config.yml and run the wazuh-install.sh script to install the new server nodes as it's referred to in the
documentation.
Let me know if it helped you!
Regards,
Manuel.
